The LC05711ARA is a protection IC for 1-cell lithium-ion secondary batteries with integrated power MOSFET. Also it integrates highly accurate detection circuits and detection delay circuits to prevent batteries from over-charging, over-discharging, over-current discharging and over-current charging. A battery protection system can be made by only LC05711ARA and few external parts.
Charge-and-discharge power MOSFET are integrated - Easy design
ON resistance (total of charge and discharge ) 4.8 mΩ (typ) - Low power dissipation
Highly accurate detection voltage/current at Ta = 25°C, VCC = 3.7 V
Over-charge detection ±25 mV
Over-discharge detection ±50 mV
Charge over-current detection ±0.7 A
Discharge over-current detection ±0.7 A - High accurate detection
Discharge/Charge over-current detection is compensated for temperature dependency of power FET - Accurate control
ECP30 WLP package - Small package
1-cell Lithium-ion Secondary Batteries Protection
